Genetic analysis of the 60.2-kb lactococcal plasmid pMRC01 revealed a 19.6-kb region which includes putative genes for conjugal transfer of the plasmid and a sequence resembling an origin of transfer (oriT). This oriT-like sequence was amplified and cloned on a 312-bp segment into pCI372, allowing the resultant plasmid, pRH001, to be mobilized at a frequency of 3.4 x 10(-4) transconjugants/dono...

Use of ZnO at high doses (3000 ppm) for diarrhea prophylaxis in piglets is widely extended in postweaning Spanish diets, in compliance with the national veterinary regulation. However, European feed legislation limits total dietary Zn to a maximum of 150 mg/kg of complete feed. The objective of this study was to compare a new potentiated form of ZnO, HiZox (Animine), at nutritional level (150 p...

AIM The aim was to investigate the effects of dietary supplementations of prebiotic, probiotic, and synbiotic on growth performance and carcass characteristics of broiler chickens. MATERIALS AND METHODS A total of 360 1-day-old Vencobb broiler chickens of either sex were randomly assigned to four dietary treatments each consisting of three replicates and each replicate having 30 birds for 6 w...

Morphological, biochemical and molecular characteristics were studied to identify dominant lactic acid bacteria (LAB), isolated from traditional yoghurts produced by tribes of Iran. From 60 yoghurt samples, a total of 137 LAB isolates were determined, in which 66 and 71 were identified as lactic acid cocci and bacilli, respectively. Biochemical tests showed the occurrence of 9.76% mesophilic ho...

We offer a tractable model of broadcast media as a three-sided platform, serving entertainment and news to viewers, commercial opportunities to advertisers, and electoral influence to politicians. We characterize the profitmaximization decision of a media firm, and study the effect on social welfare of changes in the value of electoral influence, via induced changes in commercial advertising, t...

Living in a world where environment protection and energy conservation are the first worries, the development of hybrid vehicle seems to be an accelerated pace. There for, recent efforts are directed toward developing an improved propulsion system. One of the most valuable solutions is the starter alternators [19]. This paper presents an advanced development of a switched reluctance starter-alt...
